Servo aims to provide an independent, modular, embeddable web rendering engine, allowing developers to deliver content and applications using web standards.

Created by Mozilla Research in 2012, the Servo project is a research and development effort. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. In 2023 the project moved to Linux Foundation Europe.

Servo is written in Rust, taking advantage of the memory safety properties and concurrency features of the language.

Since its creation in 2012, Servo has contributed to W3C and WHATWG web standards, reporting specification issues and submitting new cross-browser automated tests, and core team members have co-edited new standards that have been adopted by other browsers. As a result, the Servo project helps drive the entire web platform forward, while building on a platform of reusable, modular technologies that implement web standards.


Servo’s roadmap is defined in the project wiki: https://github.com/servo/servo/wiki/Roadmap

Servo roadmap for 2024 with the following tasks expanding the whole year: project maintenance and outreach, CSS support, embedding API definition and initial Android support

WPT pass rates

The chart below tracks our pass rates in several focus areas of the Web Platform Tests, as well as the whole CSS and WPT test suites. To drill down the pass rates under a focus area, see the Servo results on wpt.fyi, or for more details and legacy layout scores, see our full WPT dashboard at wpt.servo.org.
